Description

Analysis Note

The xylene isomers are precursors to many chemicals:

  • o-xylene is a precursor for phthalic anhydride
  • m-xylene is a precursor for isophthalic acid
  • p-xylene is a precursor for terephthalic acid and dimethyl terephthalate

The cresol (methylphenol) isomers are also precursors to many chemicals. This chromatogram of a mix of aromatic and methylphenol compounds was generated using an SLB-IL60 ionic liquid column. Its interaction mechanisms allow the separation of all three xylene isomers, and all three cresol isomers.
